To all whom t may concern: l

Be it known that l, HUGH PARTRIDGE, a citizen of the United States, residing at Ortega, in the county of Duval and State of Florida, have invented a new and useful Sprinkler, of which the following'- is a speciication. 1

rThe present invention appertains to lsprinklers such as are used for watering grass, plants or other vegetation, and it is the object of the invention to provide a rotary sprinkler of novel and' improved construction. Y

It is the object of the invention to provide a sprinkler 'which will have a relatively slow speed of rotation due to the arrangement'of the outlet apertures, whereby-the water will be projected in a more effective manner than ordinarily, to cover a `larger area, and to distribute thev water evenly akin to that of rain. v i v It is also within the scope of theinvention to provide a sprinkler having the characteristics above noted, and which is compara' tively simple and inexpensive in construcltionand manufacture, as well as being practical and eficient in use.

With the foregoing and other obJects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and 1n the details of construction hereinafter described and' claimed, it being understood.

that changes in the precise embodiment of the invention herein disclosed can be made within the scope of `what is claimedwitln out Adeparting from the spirit of the invention. rilhe invention is illustrated in the accom panying drawing, wherein e Figure l is a plan view of the sprinkler. Fig. 2 is a central vertical section thereof. In carrying out the invention, thereis provided a horizontal discharge pipe-lcon structed of brass or other suitable mat e rial, andl having its ends closed by plugs 2.

A sleeve 3 of suitable metal is cast or fitted upon the central portionl of "the p1pe`1, to act as a weight forcounteracting the thrust created rby the pressure of the water, said A sleeve being of any 4suitable weight. `The Asleeve 3 and central portion of `the pipe 1 are provided with a lower threaded aperture 4 threadedly receiving the upper end of a vertical tubular member 5 for deliver ing the water into the pipe l.

The tubular member 5 is mounted for rotation within the upper reduced portion 6 .portion 6 are provided with counter bores 9 in which bushings 8 are fitted, the tubular member 5l being journaled in said bushingsv 8. The space between the bushings 8 can be filled with lubricant, for lubricating the contacting portions of the member 5 and bushings, so as to reduce friction and wear. Collars or nuts 10 are engaged upon the lower end of the member 5 to cop'erate with the lower bushing 8 forlhoiding the member 5 in place.

A salient feature of the invention resides in the peculiar arrangement of the outlet apertures or oriiices 11 Ain the pipe l, each arm of said pipe having a helical series of apertures 11. The inner apertures of the two vseries are arranged adjacent the sleeve 3 and are disposed at the top or crest of the pipe l so as to discharge the water vertically. The apertures of one arm extend from the top to one side of said arm adjacent the free end of said arm, so that the outer aperture 11 discharges the water horizontally or tangentially relative to the path of rotation, while the intermediate apertures of said arm discharge the water at various angles above the horizontal' plane of rotation.7 The apertures of the other arm extend along a helical line of greater pitch than the helical line along which the apertures of the first mentioned arm extend, Awhereby the outer aperture 11 of the second `mentioned arm directs the water upwardly at an angle above the horizontal plane of rotation, while the intermediate apertures of the second mentioned arm direct the water at a greater` angle upwardly. It will be observed that lis arranged, the'other side of the pipe being imperforate, so' that the water is' dis'- l charged to oneside-of the pipe l from either" arm thereof. However, Vsince the apertures of one arm extend downwardly closer to the horizontal plane ofrotation, the reaction of the water discharged from the respective The present sprinkler is adaptedfor usev in overhead irrigation, the sprinklers being attached at suitable'intervals to waterpipes extended over theground to be irrigated, although the sprinkler may beused for watering. lawns, or the like; The sprinkler can be inexpensively manufactured so that the sprinklers can be provided at suitable distances over an entire farm, without entailing prohibitive expense. With an ordinary sprinkler, the water is discharged from each arm in the same direction relative to the direction lof rotation whereby thewater is delivered to the vegetation at the same angle, whereas with lthe present device, the water is delivered from one arm at one angle to the vegetation, and is delivered at the opposite angle -from the opposite arm,

which results in the even distribution and watering of the plants akin to that of rain.

` The water will thus be sprayed to all sides .of the plants, while with ordinary sprinklers it is generally the' case that the plants are left dry upon one side. Due to the fact that the'reaction of the discharged water atthe opposite Aarms tends to counteract one another, the water is discharged a greater distance from the pipe, so that a greater area will be watered than with the use of an ordinary sprinkler, it beingunderstood that the water can be discharged farther from a stationary or slowly revolving member, than from a member which rotates faster due to the reaction of the water, since the faster the member is rotated by the reaction of the water, the less will the water be thrown from the said member. The arrangement of the apertures is therefore of advantage in several respects, viz., it provides for the relatively slow speed of rotation of the pipe or head, it facilitates the projection of the water from the pipe, it increases the area covered by the water even with a lower pressure, and it results in the water being evenly distributed akin to that of rain. The apertures nearest the center of the pipe throw the water upwardly so that it will fall around the sprinkler, and the farther away from the center of the pipe the apertures are, the farther will the water be thrown from the sprinkler, to assure the uniform Watering of the area at the center of which the sprinkler is arranged.

l'Having thus described the invention', what is claimed as new is:

A sprinkler embodying a horizontal pipe having its ends closed, a vertical pipe having its `upper end attached to the central portion of the horizontal pipe and mounted for rotation about a vertical axis, the horizontal pipe having opposite arms and said arms each having a series of apertures extending a-long a helical line, the inner apertures being at they top of the pipe4 and one helical line being of greater pitch than the other so that the outer aperture of one series I is disposed at one side of the respective arm to discharge the water approximately horizontally while the outer aperture of the other series discharges the water upwardly at .an angle, thev intermediate apertures `all discharging the water upwardly at an angle to the same side of the pipe.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

HUGH PARTRIDGE.
